Explanation:

Soil is a natural resource that may look robust and endless, but is in fact the fragile product of thousands of years of formation. Topsoil, which lies closest to the surface of the land, contains essential nutrients for crops. It is this layer of soil that is endangered by wind and water erosion. Soil erosion decreases soil fertility, which can negatively affect crop yields. It also sends soil-laden water downstream, which can create heavy layers of sediment that prevent streams and rivers from flowing smoothly and can eventually lead to flooding. Once soil erosion occurs, it is more likely to happen again.

This is a global problem. Soil is eroding more quickly than it is being formed, causing land to become unsuitable for agriculture – a particularly serious concern in a world where the population is expected to top 9 billion by midcentury. Smarter land management is a necessity.

Answer:

soil erosion can remove the top most fertile soil which is rich in minerals and without sufficient minerals the crops won't be able to grow properly , hence it limits the use of land as a resource

1. Planting a cover crop - Between harvesting one crop and planting the next crop, the fields lie bare; there is a time period when the farmland does not have any crops. During this period, the farmer either grows grass or grows other crops to prevent soil from erosion. This helps the soil to regain the lost minerals.

2.Afforestation. Planting new trees and plants is afforestation

3.Terrace Farming - In hilly areas, farming is done by cutting steps on the slopes of the hills. This slows down the flow of water and soil removed from one step is deposited on the next step. Thus, the soil is never completely lost. This is terrace farming.
